Did Cooper keep the lights off in the cabin? I've been reading about McCoy's jump. it's so much different than what Cooper did. after reading it, you have to wonder if Cooper even had a plan where he was going to jump. if you ask me, it points again that he was going to jump early?
"The hijacker opened his luggage and covered the peephole between the cockpit and cabin. Observed by Second Officer Floyd Smith (fictitious name) through a slight space under the cockpit door, the hijacker quickly put on a jumpsuit, helmet, and parachute. Once he had shut off the cabin lights to better view the ground, the gunman demanded to be kept abreast of wind, ground, and air speeds; altimeter settings; and sky conditions."
